- the invention relates to a multi-gas system according to the preamble of claim 1. This comprises a number of highly developed technical advantages, which as such means a considerable reduction in manufacturing costs and manufacturing times, which in turn naturally leads to a significant reduction in the sales prices for these articles.
- valve groups through which the gas reaches the burners of the gas stoves, the heaters or any other devices which are used for more than one purpose, as well as the distribution of this gas in the form of stationary and rigid monoblock systems, are manufactured that as a result of this immobility in manufacturing they cannot find a wide range of applications.
- the disadvantage of this is that the distance between the individual gas taps is predetermined by the monoblock and cannot be changed.
- the gas line is integrated in the monoblock. Therefore, a separate monoblock is required for each application and, moreover, the individual gas taps must be fitted tightly into the monoblock, which makes it difficult to assemble.
- a disadvantage of this is in particular that the screwed sleeves must have narrow tolerances in length so that the intended O-ring fulfills its sealing function. Therefore, the assembly of the gas taps is relatively difficult.
- EP-A-0 205 655 describes a compact complex of multi-gas valves which can be mutually adapted via a threaded sleeve and O-rings, which favor the sealing of the connections.
- a connection method is cumbersome, especially since great precision must be used in production in order to align the drive stems of the valves parallel to one another, because the distance between the drive stems of these valves is always a rigid distance.
- the object of the invention is to develop the known multi-gas system so that not only the assembly is simplified, but also the above. Disadvantages of the prior art can be avoided.
- the present invention has now overcome all those shortcomings which existed in EP-A-0 205 655 as well as before, and gas valve complexes of simple design were developed which can be connected to one another by lines of any length and thus adaptable to each Configuration, can be connected, whereby the connection between the valves, after they have been installed in the application in question, is made considerably easier by a quick-release fastener.
- Figure 1 shows a plan view from above of such a valve element with parallel gas outlet or on-line with the drive shaft, with special emphasis on level A-A ′.
- Figure 2 shows the same valve of Figure 1 in cross section of the sectional plane A-A '.
- Figure 3 shows the connection of preferably three valves to each other via the quick coupling system.
- Figure 4 shows a plan view from above of a valve element according to the present invention, with a gas outlet perpendicular to the drive shaft, highlighting the plane B-B '.
- Figure 5 shows the valve shown in Figure 4 in cross section through the section plane B-B ′.
- Figure 6 shows the optional connection of three Valves similar to those shown in Figure 4.
- FIG. 1 the top view and the cross-sectional view of the valve element are shown with a gas outlet parallel and on-line to the drive shaft.
- 1 is said stem, which is bound to the central element of valve 3 via intermediate body 2.
- This shaft has a safety drive system which allows the drive of this system only via or when the shaft is pressurized inwards after overcoming the return spring force 4, as a result of which the shaft is able to rotate the closure element 5, which is broken through in the central region 6 and which is connected to a lateral section 7, which has the task of enabling the passage from the main gas duct 8 to the outlet line 9, which can be connected in connection with the burner until it is used.
- Position 10 shows the regulating screw for the minimum gas throughput or the pilot flame, which throttles the outlet line 11 and, depending on the stronger or lesser suit, causes a greater or lesser gas throughput in connection with the minimum throughput for the gas outlet, or up to one fixed minimum over the intended opening.
- Figure 3 shows the connection of three valves 12, 13 and 14, although a connection with a larger number of valves is also possible.
- the connection to one another takes place via the lines 15 to 18, the length of which can be varied and which are fastened under pressure to the valve bodies 12, 13 and 14. In this way, this connection takes place more safely and quickly, without a screwing-in process or a connection via fastening flanges or other fasteners known to date.
- Figures 4 and 5 are a top view and a cross-sectional view through the plane B-B ', where the gas outlet 18 is arranged perpendicular to the drive shaft 19.
- this stem 19 is held over the upper body 20 and conforms to the top of the central body of the valve 21.
- this shaft 19 displaces the closure element 22, which is broken through in the outermost section, and leans against the lateral end face via the lateral line 24, as a result of which a connection between the main gas supply line 27 and the outlet line to the consumer 18 can be established.
- Position 25 shows the regulating screw for the minimum gas throughput to the consumer, e.g. the pilot flame or any other minimum gas consumption point, etc.
- This screw 25 depending on its tightening, more or less complicates the passage of gas through the line 26 or to a predetermined minimum thanks to an opening made for this purpose.
- Figure 6 shows the connection - preferably 3 valve complexes 28, 29 and 30 - via the coupling sleeves 31 to 34; these are connected to the valve body via a quick coupling system which considerably facilitates the connection to the separation of the valves from one another after the valves have already been connected to the housing of the cooker for use.
- These coupling sleeves can be designed in any length or configuration and are only restricted by the safety standards which are contained in the respective statutory regulations of the countries.
- connection between the valves can primarily be made at the desired distance, for which purpose the said more or less long interconnection sleeves have to be attached; secondly, it is not necessary to arrange the valve complexes in parallel or in the same plane, because by arranging the sleeves accordingly, they can be adapted accordingly. Thirdly, an indefinite number of valves can be provided for practical use, since these are not a rigid and compact monoblock. Finally, thanks to the interconnection system of the individual valves with each other, the connection and the final conception of the entire complex can be accomplished through a considerable saving of time and material, which leads to a significant advantage compared to the methods and elements which are according to the current state of the art usually used.

Abstract
Description
Die Erfindung betrifft ein Multigassystem nach dem Oberbegriff des Anspruchs 1. Dieses umfaßt eine Reihe hochentwickelter technischer Vorteile, die als solche eine erhebliche Verringerung der Herstellungskosten und Herstellungszeiten bedeutet, was wiederum naturgemäß zu einer deutlichen Senkung der Verkaufspreise für diese Artikel führt.The invention relates to a multi-gas system according to the preamble of
Zur Zeit werden die Ventilgruppen, über die das Gas zu den Brennern der Gasherde, der Heizgeräte oder irgendwelcher anderer Einrichtungen gelangt, die für mehr als einen Verwendungszweck eingesetzt werden, wie auch die Verteilung dieses Gases in Form stationärer und starrer Monoblock-Systeme hergestellt, so daß sie als Folge dieser Unbeweglichkeit bei der Herstellung kein breites Anwendungsfeld finden können.At the moment, the valve groups through which the gas reaches the burners of the gas stoves, the heaters or any other devices which are used for more than one purpose, as well as the distribution of this gas in the form of stationary and rigid monoblock systems, are manufactured that as a result of this immobility in manufacturing they cannot find a wide range of applications.
Aus der FR - A - 859 980 ist es bekannt, die einzelnen Gashähne in einem Monoblock anzuordnen die damit den vorgegebenen Abstand voneinander einnehmen müssen.From FR-A-859 980 it is known to arrange the individual gas taps in a monoblock, which must therefore take up the predetermined distance from one another.
Nachteilig hieran ist, daß der Abstand der einzelnen Gashähne durch den Monoblock vorgegeben ist und nicht geändert werden kann. Die Gasleitung ist in den Monoblock integriert. Deshalb ist für jeden Einsatzzweck ein separater Monoblock erforderlich und außerdem müssen die einzelnen Gashähne dicht in den Monoblock eingepaßt werden, wodurch dessen Montage erschwert wird.The disadvantage of this is that the distance between the individual gas taps is predetermined by the monoblock and cannot be changed. The gas line is integrated in the monoblock. Therefore, a separate monoblock is required for each application and, moreover, the individual gas taps must be fitted tightly into the monoblock, which makes it difficult to assemble.
Dieses Problem tritt auch bei der EP-A-0 205 655 auf. Hier sitzen ebenfalls die einzelnen Gashähne mit gleichen Abständen in einem Formkörper. Diese Abstände werden ebenfalls fest vorgegeben und können nicht geändert werden.This problem also occurs with EP-A-0 205 655. Here, too, the individual gas taps are seated at the same distance in a molded body. These distances are also predefined and cannot be changed.
Nachteilig hieran ist insbesondere, daß die geschraubten Muffen eng tolerierte Längenabmessungen besitzen müssen, damit der vorgesehene O-Ring seiner Dichtfunktion gerecht wird. Deshalb ist auch die Montage der Gashähne relativ schwierig.A disadvantage of this is in particular that the screwed sleeves must have narrow tolerances in length so that the intended O-ring fulfills its sealing function. Therefore, the assembly of the gas taps is relatively difficult.
In der EP-A-0 205 655 wird ein kompakter Komplex aus Multigas-Ventilen beschrieben, die gegenseitig über eine Gewindemuffe und O-Ringe angepaßt werden können, die die Abdichtung der Verbindungen begünstigen. Ein solches Verbindungsverfahren ist jedoch umständlich, zumal bei der Herstellung mit großer Präzision gearbeitet werden muß, um die Antriebsschäfte der Ventile parallel zueinander auszurichten, denn der Abstand zwischen den antriebsschäften dieser Ventile ist stets ein starrer Abstand.EP-A-0 205 655 describes a compact complex of multi-gas valves which can be mutually adapted via a threaded sleeve and O-rings, which favor the sealing of the connections. However, such a connection method is cumbersome, especially since great precision must be used in production in order to align the drive stems of the valves parallel to one another, because the distance between the drive stems of these valves is always a rigid distance.
Aufgabe der Erfindung ist, das bekannte Multigassystem so weiterzubilden, daß nicht nur die Montage vereinfacht wird, sondern auch die o.g. Nachteile des Standes der Technik vermieden werden.The object of the invention is to develop the known multi-gas system so that not only the assembly is simplified, but also the above. Disadvantages of the prior art can be avoided.
Diese Aufgabe wird gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved by the characterizing features of
Durch die vorliegende Erfindung wurden nun all jene Mängel beseitigt, die bei der EP-A-0 205 655, wie auch davor, bestanden haben, und es wurden Gas-Ventilkomplexe einfacher Konzeption entwickelt, die untereinander durch Leitungen jedweder Länge und somit anpassungsfähig an jede Konfiguration, verbunden werden können, wobei durch einen Schnelldruckverschluß die Verbindung zwischen den Ventilen, nachdem sie in dem betreffenden Anwendungsfall montiert worden sind, erheblich erleichtert wird.The present invention has now overcome all those shortcomings which existed in EP-A-0 205 655 as well as before, and gas valve complexes of simple design were developed which can be connected to one another by lines of any length and thus adaptable to each Configuration, can be connected, whereby the connection between the valves, after they have been installed in the application in question, is made considerably easier by a quick-release fastener.
Um nun den Wesensinhalt der vorliegenden Erfindung ausführlicher zu beschreiben, sei auf die beigefügten Zeichnungen verwiesen, wo als mögliches Beispiel, und ohne daß damit alle Möglichkeiten erschöpft sein würden, einige vorzugsweise Formen der Verwirklichung des Erfindungsgedankens dargestellt werden.In order to describe the essence of the present invention in more detail, reference is made to the attached drawings, where as a possible example and without exhausting all possibilities, some preferred forms of realizing the inventive idea are shown.
Abbildung 1 zeigt eine Grundrißansicht von oben eines solchen Ventilelements mit parallelem Gasaustritt oder on-line mit dem Antriebsschaft, unter besonderer Betonung der Ebenee A-A′.Figure 1 shows a plan view from above of such a valve element with parallel gas outlet or on-line with the drive shaft, with special emphasis on level A-A ′.
Abbildung 2 zeigt das gleiche Ventil der Abbildung 1 im Querschnitt der Schnittebene A-A′.Figure 2 shows the same valve of Figure 1 in cross section of the sectional plane A-A '.
Abbildung 3 zeigt die Verbindung von vorzugsweise drei Ventilen untereinander über das Schnellkopplungssystem.Figure 3 shows the connection of preferably three valves to each other via the quick coupling system.
Abbildung 4 zeigt eine Grundrißansicht von oben eines Ventilelements gemäß der vorliegenden Erfindung, mit einem Gasaustritt senkrecht zum Antriebsschaft, unter Hervorhebung der Ebene B-B′.Figure 4 shows a plan view from above of a valve element according to the present invention, with a gas outlet perpendicular to the drive shaft, highlighting the plane B-B '.
Abbildung 5 zeigt das in der Abbildung 4 dargestellte Ventil im Querschnitt durch die Schnittebene B-B′.Figure 5 shows the valve shown in Figure 4 in cross section through the section plane B-B ′.
Abbildung 6 zeigt die wahlweise Verbindung von drei Ventilen ähnlich jenen, die in Abbildung 4 dargestellt worden sind.Figure 6 shows the optional connection of three Valves similar to those shown in Figure 4.
In den vorstehend erwähnten Abbildungen 1 und 2 werden die Draufsicht und die Querschnittsansicht des Ventilelements mit einem Gasaustritt parallel und on-line zu dem Antriebsschaft aufgezeigt. Dabei ist 1 der besagte Schaft, der über den Zwischenkörper 2 an das zentrale Element des Ventils 3 gebunden ist. Dieser Schaft verfügt über ein Sicherheits-Antriebssystem, das den Antrieb dieses Systems nur über oder bei einer Druckeinwirkung des Schafts nach innen nach Überwindung der Rückholfederkraft 4 ermöglicht, wodurch es dem Schaft gelingt, das Verschlußelement 5 zu drehen, das im mittleren Bereich 6 durchbrochen ist und das an einen seitlichen Abschnitt 7 angebunden ist, der die Aufgabe hat, den Durchgang von der Hauptgasführung 8 bis zur Ausgangsleitung 9 zu ermöglichen, die bis zu deren Einsatz in Verbindung mit dem Brenner anschließbar ist.In figures 1 and 2 mentioned above, the top view and the cross-sectional view of the valve element are shown with a gas outlet parallel and on-line to the drive shaft. 1 is said stem, which is bound to the central element of
In der Position 10 wird die Regelschraube für den Mindestgasdurchsatz bzw. die Pilotflamme dargestellt, die die Ausgangsleitung 11 abdrosselt und die, je nach stärkerem oder geringerem Anzug, einen stärkeren oder geringeren Gasdurchsatz in Verbindung mit dem Mindestdurchsatz für den Gasaustritt bewirkt, oder bis zu einem feststehenden Minimum über die vorgesehene Öffnung.
In Abbildung 3 wird die Verbindung dreier Ventile 12, 13 und 14 dargestellt, wenngleich eine Verbindung auch mit einer größeren Anzahl von Ventilen möglich ist. Die Verbindung untereinander erfolgt dabei über die Leitungen 15 bis 18, deren Länge variabel gestaltet werden kann und die unter Druck an den Ventilkörpern 12, 13 und 14 befestigt werden. Auf diese Art und Weise erfolgt diese Verbindung sicherer und schneller, ohne einen Einschraubvorgang oder eine Verbindung über Befestigungsflansche oder sonstige bis heute bekannte Befestigungselemente.Figure 3 shows the connection of three
Bei den Abbildungen 4 und 5 handelt es sich um eine Draufsicht und eine Querschnittsansicht durch die Ebene B-B′, wo der Gasaustritt 18 senkrecht zum Antriebsschaft 19 angeordnet ist. Wie bei den vorausgegangenen Abbildungen wird dieser Schaft 19 über den oberen Körper 20 festgehalten und paßt sich oben an den zentralen Körper des Ventils 21 an. Dieser Schaft 19 verdrängt bei seiner Kreisbewegung das Verschlußelement 22, das im äußersten Abschnitt durchbrochen ist und lehnt sich über die seitliche Leitung 24 an die seitliche Stirnfläche an, wodurch eine Verbindung zwischen der Hauptgas-Versorgungsleitung 27 und der Ausgangsleitung zum Verbraucher 18 hergestellt werden kann.Figures 4 and 5 are a top view and a cross-sectional view through the plane B-B ', where the
Die Position 25 zeigt die Regelschraube für den Mindestgasdurchsatz an den Verbraucher, wie z.B. der Pilotflamme oder irgendeiner anderen Gas-Mindestverbrauchsstelle usw. Diese Schraube 25 erschwert, je nach ihrem Anzug, mehr oder weniger den Gasdurchgang durch die Leitung 26 bzw. bis zu einem im voraus festgelegten Minimum dank einer zu diesem Zweck eingearbeiteten Öffnung.
In Abbildung 6 wird die Verbindung - vorzugsweise 3 Ventilkomplexe 28, 29 und 30 - über die Kupplungsmuffen 31 bis 34 dargestellt; diese werden an den Ventilkörper über ein Schnellkopplungssystem angeschlossen, das den Anschluß an die Trennung der Ventile untereinander erheblich erleichtert, nachdem die Ventile bereits an das Gehäuse des Herds für den Einsatz angeschlossen sind. Diese Kopplungsmuffen können in jeglicher beliebigen Länge oder Konfiguration ausgebildet werden und werden nur durch die Sicherheitsnormen eingeschränkt, die in den jeweiligen Gesetzesverordnungen der Länder enthalten sind.Figure 6 shows the connection - preferably 3
Somit kann, wie man hieraus erkennt, die Verbindung zwischen den Ventilen in erster Linie in dem jeweils gewünschten Abstand vorgenommen werden, zu welchem Zweck man die besagten mehr oder weniger langen Zwischenverbindungsmuffen anzubringen hat; zweitens ist es nicht erforderlich, die Ventilkomplexe parallel oder in der gleichen Ebene anzuordnen, denn indem man die Muffen entsprechend anordnet, können sie entsprechend angepaßt werden. Drittens kann eine unbestimmte Anzahl von Ventilen für den praktischen Einsatz vorgesehen werden, da diese ja keinen starren und kompakten Monoblock darstellen. Schließlich kann dank des Zwischenverbindungssystems der einzelnen Ventile untereinander, der Anschluß und die endgültige Konzeption des gesamten Komplexes durch eine erhebliche Zeit- und Materialeinsparung bewerkstelligt werden, was zu einem wesentlichen Vorteil im Vergleich zu den Verfahren und Elementen führt, die nach dem derzeitigen Stand der Technik üblicherweise zum Einsatz gelangen.Thus, as can be seen from this, the connection between the valves can primarily be made at the desired distance, for which purpose the said more or less long interconnection sleeves have to be attached; secondly, it is not necessary to arrange the valve complexes in parallel or in the same plane, because by arranging the sleeves accordingly, they can be adapted accordingly. Thirdly, an indefinite number of valves can be provided for practical use, since these are not a rigid and compact monoblock. Finally, thanks to the interconnection system of the individual valves with each other, the connection and the final conception of the entire complex can be accomplished through a considerable saving of time and material, which leads to a significant advantage compared to the methods and elements which are according to the current state of the art usually used.
